Hi! This might answer your question: https://webmasters.stackexchange.com/questions/67654/seo-if-another-website-uses-a-iframe-from-our-website-would-the-links-in-the-i It was a little ambiguous which method you were going to use for the embed code, if you were planning to have others embed via iframe, then the links would be you to you.  In that case, it may hurt your site if a more popular site is treated as a canonical and is indexed instead of yours.
